I want to see if single speaker cable with jumper as good as bi wire cable can be
I had both single and shotgun biwire versions of my speaker cables and although I slightly preferred the shotgun pair I’d say your incremental $$$ would be better spent on good jumpers rather than going biwire and then use the considerable savings elsewhere in your system. To me, the main benefit of biwire is the additional gauge, but as your cables are already 10AWG I wouldn’t think that’d be all that much of a benefit in your case. Hope that helps a little.
